S203、Client A向Cloud A发送获取Cloud A上设备信息的请求。
在一些实施方式中，Client A与Cloud A之间的连接可以是短连接或长连接。本申请实施例中的Client A可以是上述的客户端。在一些实施例中，Client A与Cloud A之间或者Device A与Cloud A之间在建立安全连接后进行数据传输，例如可以采用HTTP协议、CoAP协议或者MQTT协议等建立安全连接，从而在Client A与Cloud A之间或者Device A与Cloud A之间可以建立安全通道，进 而数据或信息可以在Device A与Cloud A之间安全传输。
设备信息可以包括在Cloud A上的所有设备的信息，或者，包括与Client A相关联的设备的信息。设备信息可以包括至少一个设备的设备信息。
S205、Cloud A向Client A发送Cloud A上的设备信息。
Cloud A上的设备信息可以包括Device A的设备信息。在一些实施例中，Cloud A上的设备信息可以包括Device B、Device C、Device D等中的至少一个的设备信息。
Device A上可以包括至少一个资源，一个资源可以包括至少一个资源信息。
例如，在Device A为电灯时，电灯中可以包括至少一个资源，例如，电灯中可以包括用于控制电灯亮度的资源、用于控制电灯的颜色的资源、用于控制电灯的色温的资源、用于控制电灯的闪烁频率的资源等中的至少一个。
再例如，在Device A为洗衣机时，洗衣机可以包括至少一个资源，例如，洗衣机中可以包括用于控制洗衣模式的资源、用于控制水位高度的资源、用于控制洗衣时长的资源、用于控制漂洗强度的资源等中的至少一个。
又例如，在Device A为电视机时，电视机可以包括至少一个资源，例如，电视机中可以包括用于控制电视机播放频道的资源、用于控制播放声音大小的资源、用于调整显示模式的资源等中的至少一个。
应当理解，Device A还可以用其它设备进行举例，例如空调、音箱或水壶等，本申请实施例对Device A的实现场景不作限定。
例如，Cloud A向Client A发送Cloud A上电灯、洗衣机、电视机、空调、音箱或水壶等至少一个设备的设备信息。
设备信息中不仅可以包括设备中包括的至少一个资源或至少一个资源的标识，还可以包括设备类型、设备标识、设备外观、设备位置等中的至少一个信息。
S207、Client A向Cloud A发送订阅请求，该订阅请求用于请求订阅Cloud A上Device A的资源信息。
在一些实施例中，Client A可以请求订阅一个设备的资源信息，或者，可以请求订阅至少两个设备的资源信息，一个设备或至少两个设备的资源信息包括Device A的资源信息。在一些实施例中，Client A可以请求订阅一个设备的一个资源的资源信息，或者，可以订阅一个设备的至少两个资源的资源信息。
S209、Cloud A向Device A发送订阅请求，该订阅请求用于请求订阅Cloud A上Device A的资源信息。
S211、Device A向Cloud A发送订阅成功消息和当前资源信息。
在一些实施例中，订阅成功消息和当前资源信息可以是在一个信令中发送的。在另一些实施例中，订阅成功消息和当前资源信息可以分别是在两个信令中发送的，例如，订阅成功消息可以先于当前资源信息发送，或者，当前资源信息可以先于订阅成功消息发送。
S213、Cloud A向Client A转发订阅成功消息和当前资源信息。
S215、Device A资源状态改变。
以资源设备为洗衣机为例，资源状态改变例如是洗衣机的工作模式改变、洗衣机的水位信息、洗衣机的漂洗强度的改变中的至少一个。
S215、Device A向Cloud A发送改变后的资源信息。
S217、Cloud A向Client A发送改变后的资源信息。
相关技术只是提供了Device A如何向Client A上报资源状态的情况，相关技术并未考虑到在Device A断电重启后如何运行的情况。
以一个实施场景进行举例，在洗衣机正在采用正常洗衣模式进行洗衣服的过程中，如果洗衣机断电上电后(例如是重启的断电上电，或者停电导致的断电上电，或者是用户误操作导致的断电上电等)，洗衣机可能会处于关机状态、待机状态或者以默认状态运行，如此，洗衣机在断电上电后，无法接着断电上电前的状态继续运行。
以另一个实施场景进行举例，在洗衣机以正常模式进行洗衣时，如果用于切换到快洗模式后，又想重新切换至正常模式，这时需要用户进行复杂的操作才能重新恢复到正常模式，导致用户的操作麻烦。
再例如，在空调在检测到周围温度满足设定的温度时，会进入省电模式或者待机模式，然而，在很多场景下，用户希望空调一直以固定的状态进行工作，而不希望空调突然进入其它状态，然而， 用户的这种需求只会使得用户不停地使用空调遥控器对空调进行遥控操作，导致用户的使用麻烦。
图3为本申请实施例提供的一种物联网通信方法的流程示意图，如图3所示，该方法包括：
S301、客户端通过云平台接收资源设备发送的第一资源信息；第一资源信息包括或指示资源设备中特定资源的第一资源状态信息。

在一些实施例中，资源设备可以通过云平台向客户端以固定周期发送资源信息。在另一些实施例中，资源设备可以通过云平台向客户端以可变周期发送资源信息，例如，在6:00-24:00之间，资源设备可以采用较短的周期发送资源信息，在0:00-6:00之间，资源设备可以采用较长的周期发送资源信息。再例如，在资源设备确定家庭中存在用户时，可以采用较短的周期发送资源信息，在资源设备确定家庭中不存在用户时，可以采用较长的周期发送资源信息。其中，第一资源信息可以是资源设备通过云平台向客户端发送的当前的资源信息。
资源设备通过云平台向客户端发送的每一个资源信息(可以是图2对应的实施例中的资源信息，包括本申请实施例中描述的第一资源信息、第二资源信息或第三资源信息)中可以包括或指示特定资源的资源状态信息，或者，可以包括或指示特定资源的资源状态信息和特定资源的资源属性信息。特定资源的资源状态信息可以是特定资源的当前状态值，通常会随着特定资源状态的变化而产生变化。在资源设备通过云平台向客户端发送的每一个资源信息中的资源属性信息，可以包括以下至少一个：资源信息/资源状态信息是否可恢复、资源信息/资源状态信息的类型、资源信息/资源状态信息是否可修改、资源信息/资源状态信息所对应的特定资源的标识等。
例如，第一资源信息可以不仅包括第一资源状态信息，还可以包括特定资源的资源属性信息。在本申请实施例中，资源设备通过云平台向客户端发送的每一个资源信息，例如第一资源信息或下述的第二资源信息、第三资源信息等，均可以包括特定资源的资源属性信息，或者，部分资源信息包括特定资源的资源属性信息。
本申请实施例中的第一资源信息(或者下述的第二资源信息或第三资源信息)可以用state表示，state可以表示特定资源的当前状态。例如，state可以包括：资源状态1：XXX；资源状态2：XXX；资源状态3：XXX；资源属性1：XXX；资源属性2：XXX。
第一资源状态信息可以是至少一个资源状态信息，至少一个资源状态信息中的每一个资源状态信息可以是资源状态值。例如，以资源设备为洗衣机，特定资源为洗衣机的工作模式进行举例，第一资源状态信息可以是洗衣机的运行模式标识、洗衣机已经运行的时长、洗衣机的水位信息、洗衣机的洗衣强度等信息中的至少一个。
特定资源可以是资源设备中的一个资源或者至少两个资源。特定资源的资源属性信息可以包括一个或至少两个属性信息，一个或至少两个属性信息的至少部分，可以是固定不变的属性信息，或者，可以是随着时间和/或场景变化而变化的属性信息，或者，可以是通过资源设备接收用户输入的属性调整操作而变化的属性信息。例如，在资源属性信息为指示(indicate)属性下的信息A(或者描述为indicate：A)时，信息A表征资源状态信息可恢复。在一些实施例中，资源属性信息可以一直为信息A。在另一些实施例中，可以在资源设备接收到某些指令时，将资源属性信息修改为信息B，信息B表征资源状态信息不可恢复。在又一些实施例中，在资源设备确定到资源信息在一段时长内恢复的次数大于阈值时，可以确定恢复出现故障，可以将资源属性信息修改为B。
S303、在第一资源状态信息变化为第二资源状态信息的情况下，客户端通过云平台向资源设备发送恢复请求；恢复请求指示资源设备将状态恢复至与第一资源状态信息对应的状态。
在本申请实施例中，第二资源状态信息不同于第一资源状态信息。
在一些实施例中，客户端可以确定第一资源状态信息变化为第二资源状态信息。为了保证恢复过程的有效性，客户端可以确定第一资源状态信息变化为其它资源状态信息后再变为第二资源状态信息的情况下，才发送恢复请求。例如，为了避免孩子的误触发对洗衣过程的影响，客户端可以在确定到第一资源状态信息在一个设定时长内发生了至少两次变化时，才向资源设备发送恢复请求。
第一资源状态信息变化为第二资源状态信息，可以是第一资源状态信息中所有的资源状态信息中的至少一个发生变化。
在一些实施方式中，客户端确定第一资源状态信息变化为第二资源状态信息，可以是客户端能 够得到具有确定的状态值的第二资源信息，从而确定第一资源状态信息变化为第二资源状态信息。在这种方式下，客户端可以接收的资源设备通过云平台发送的第二资源状态信息，从而确定第一资源状态信息变化为第二资源状态信息。
在另一些实施方式中，客户端确定第一资源状态信息变化为第二资源状态信息，可以是客户端不能得到一个具有确定的状态值的第二资源信息，只知道第一资源状态信息发生变化，但不知道第一资源状态信息发生了什么样的变化。在这种方式下，客户端可以接收资源设备通过云平台发送的用于表征第一资源状态信息发生变化的信息，或者，云平台可以确定第一资源状态信息是否发生变化，客户端可以接收云平台发送的表征第一资源状态信息是否发生变化的信息。
在一些实施例中，恢复请求可以包括第一资源信息，或者，恢复请求可以包括第一资源状态信息，在这种情况下，资源设备在状态发生变化后，可以不存储变化前的第一资源信息或者第一资源状态信息。在另一些实施例中，恢复请求可以既不包括第一资源信息，也不包括第一资源状态信息，恢复请求只是一个用于指示状态恢复的请求，在这种情况下，资源设备可以存储变化前的第一资源信息或者第一资源状态信息，在状态发生变化后，对状态进行恢复。恢复请求中是否包括第一资源信息，可以是预先设定的，或者，可以根据资源设备的属性不同而灵活性的确定。
在资源设备通过云平台接收到恢复请求时，资源设备可以响应恢复请求，将资源设备当前的资源状态信息修改为第一资源状态信息，或者将当前的资源信息修改为第一资源信息，从而使得资源设备的状态能够恢复至与第一资源状态信息对应的状态。例如，在资源设备的第一资源状态信息变化为第二资源状态信息的情况下，资源设备可以将第二资源状态信息修改为第一资源状态信息。在资源设备将资源状态信息恢复到第一资源状态信息时，资源设备就可以以与第一资源状态信息对应的状态进行运行。
依旧以洗衣机为例，洗衣机在以正常模式运行了20分钟时，如果运行模式发生了变化，变成了快洗模式或待机模式或关机模式，在洗衣机接收到恢复请求后，可以基于恢复请求，重新进入到正常洗衣模式，并接着20分钟的时间继续洗衣。
本申请实施例中，在资源设备的第一资源状态信息变化为第二资源状态信息的情况下，客户端能够通过向资源设备发送恢复请求，使资源设备的状态恢复至与第一资源状态信息对应的状态，从而在由于资源设备掉电或故障而导致资源的状态发生变化的情况下，使资源设备能够将状态恢复至之前的正常工作状态，进而能够提高物联网通信的可靠性。
图4为本申请实施例提供的另一种物联网通信方法的流程示意图，如图4所示，该方法包括：
S401、资源设备通过云平台向客户端发送第一资源信息；客户端通过云平台接收资源设备发送的第一资源信息；第一资源信息包括或指示资源设备中特定资源的第一资源状态信息。
体现在云平台侧，云平台接收资源设备发送的第一资源信息，向客户端发送第一资源信息。
S403、客户端确定第一资源状态信息变化为第二资源状态信息。
其中，第一资源状态信息对应的状态为特定资源在资源设备断电前的状态，第二资源状态信息对应的状态为特定资源在资源设备上电后的状态。
在S403之后，客户端还可以确定特定资源的资源状态能够恢复，然后再执行S405。在一些实施例中，第一资源信息还包括或指示特定资源的资源属性信息，资源属性信息用于指示特定资源的资源状态能够恢复；客户端可以基于资源属性信息，确定特定资源的资源状态能够恢复。
S405、客户端通过云平台向资源设备发送恢复请求；资源设备通过云平台接收客户端发送的恢复请求。
体现在云平台侧，云平台接收客户端发送的恢复请求，向资源设备发送恢复请求。
S407、资源设备将状态恢复至与第一资源状态信息对应的状态。
资源设备可以响应恢复请求，将状态恢复至与第一资源状态信息对应的状态。
在本申请实施例中，资源设备在发生异常时，资源设备中资源的资源状态能够复位，从而能够提高物联网通信的可靠性。另外，客户端与资源设备之间通过云平台通信的方式，由于云平台可以接入大量的客户端和资源设备，从而使得物联网***具有***扩展性强、应用范围广的优点。
图5为本申请实施例提供的又一种物联网通信方法的流程示意图，如图5所示，该方法包括：
S501、资源设备向云平台发送第一资源信息；云平台接收资源设备发送的第一资源信息。
在本申请实施例中，第一资源信息不仅包括或指示资源设备中特定资源的第一资源状态信息，还可以包括或指示特定资源的资源属性信息，资源属性信息用于指示特定资源的资源状态能够恢复。
在一些实施例中，云平台在接收到第一资源信息之后，可以基于第一资源信息的资源属性信息，确定特定资源的资源状态能够恢复。
在一些实施例中，云平台可以将存储在云平台中的第三资源信息，修改为第一资源信息；第三资源信息是云平台在第一资源信息之前接收的。
S503、云平台向客户端发送第一资源信息；客户端接收云平台发送的第一资源信息。
在一些实施方式中，云平台与资源设备在通信时所基于的协议，可以与云平台与客户端在通信时所基于的协议相同，例如，两个协议都是HTTP协议、CoAP协议或者MQTT协议。在另一些实施例中，云平台与资源设备在通信时所基于的协议，可以与云平台与客户端在通信时所基于的协议不同，例如，前者可以为HTTP协议，后者可以为CoAP协议，本申请实施例对此不作限制。
在客户端接收到第一资源信息后，可以显示与第一资源状态信息对应的状态。
在一些实施例中，客户端或云平台可以根据资源设备上报的指示资源状态是否可恢复的资源属性信息，判断该资源的可读写属性和/或可恢复属性。如洗衣机的工作模式资源下有indicate属性(只读属性)和工作模式属性(读写属性)；indicate属性指示该工作模式资源状态是否可恢复；当设备上报其资源后客户端根据indicate属性值判断该资源下的属性状态是不是可恢复的。
S505、资源设备中的第一资源状态信息变化为第二资源状态信息。
在资源设备的运行场景中，经常会出现资源设备断电上电的情况。在一种实施方式中，在资源设备上电后，资源设备的状态并不会恢复到断电之前的状态，而是进入至资源设备设置的初始状态。例如，在资源设备为电脑时，在电脑开启了多个程序的情况下，在断电上电之后，电脑并不会进入的是预先设置的桌面，并不会将断电之前开启的多个程序进行恢复。在另一种实施方式中，在资源设备上电后，资源设备的状态是可以自动进入到断电前的状态的。本申请实施例中的断电上电的一种实施方式可以是关机重启。
第二资源状态信息对应的资源设备的运行状态，可以是关机状态、待机状态或运行状态等，本申请实施例对此不作限定。
在一些实施方式中，在资源设备断电后，云平台可以监测到云平台与资源设备之间的连接断开，云平台确定资源设备离线，接着云平台可以向客户端发送资源设备离线的消息，客户端在接收到资源设备离线的消息，可以显示资源设备离线。在一些实施例中，客户端还可以对该资源设备相关的控件设置为不可触发的控件，从而用户无法通过触发客户端的方式对资源设备进行相应地控制。在一些实施例中，客户端还可以将与资源设备相关的内容采用灰度图像的方式显示，以使用户能够清楚的知道资源设备离线。
在一些实施例中，客户端是可以确定到第一资源状态变化为明确的第二资源状态的，在这种方式中，资源设备通过云平台向客户端发送第一资源信息和第二资源信息(或者第一资源状态信息和第二资源状态信息)。在另一些实施例中，客户端是不能确定到第一资源状态变化为明确的第二资源状态的，客户端只能确定到第一资源状态发生了变化，变化成了与第一资源状态不同的状态，在这种方式下，资源设备可以通过云平台向客户端发送第一资源信息(或者第一资源状态信息)，而不发送第二资源信息(第二资源状态信息)。
以下说明一种实施方式下断电上电的过程流程：在资源设备通过云平台向客户端发送了第一资源信息后，资源设备发生重启，在资源设备发生重启的过程中，云平台无法接收到资源设备发送的信息(例如，云平台无法接收到资源设备发送的心跳包)，也无法确定资源设备发生了什么事情，云平台只能确定资源设备离线，然后云平台向客户端发送资源设备离线的信息，客户端显示资源设备离线。在资源设备上电后，资源设备与云平台之间恢复连接，资源设备可以向云平台发送资源设备上线的通知，和/或，向云平台发送重启原因，重启原因例如是断电重启还是重置(reset)重启，在云平台将该上线的通知发送给客户端时，客户端可以显示资源设备上线的信息，在云平台将重启原因发送给客户端时，客户端可以显示重启原因。
S507、资源设备向云平台发送第二资源信息；云平台接收资源设备发送的第二资源信息。
第二资源状态信息用于云平台在确定第一资源状态信息和第二资源状态信息不同的情况下，向客户端发送通知消息。第二资源信息包括或指示：资源设备中特定资源的第二资源状态信息，或者，第二资源信息包括或指示：资源设备中特定资源的第二资源状态信息和特定资源的资源属性信息；资源属性信息用于指示特定资源的资源状态能够恢复。第二资源状态信息可以用于云平台在确定第一资源状态信息和第二资源状态信息不同的情况下，向客户端发送通知消息。
在一些实施方式中，资源设备可以向云平台发送资源设备上线的通知，资源设备上线的通知用于通知资源设备上线。第二资源信息与资源设备上线的通知、重启原因可以在一个信令中发送，或 者，可以在至少两个信令中发送。
在本申请实施例中，第一资源状态信息和/或第二资源状态信息可以为可读写的属性，资源属性信息可以为只读属性。
在本申请实施例中，第一资源状态信息和第二资源状态信息不同，可以用第一资源信息和第二资源信息不同来代替。
S509、云平台确定第一资源状态信息和第二资源状态信息不同。
S511、云平台向客户端发送通知消息；客户端接收云平台发送的通知消息。
通知消息指示第一资源状态信息变化为第二资源状态信息，或者，通知消息指示资源设备的资源状态需要恢复，或者，通知消息包括或者指示第一资源信息。
在一些实施例中，云平台还可以向客户端发送上线通知。
在一些实施例中，云平台可以在确定第一资源状态信息和第二资源状态信息不同的情况下，将存储于云平台中的第一资源状态信息修改为第二资源状态信息。在另一些实施例中，云平台可以在确定第一资源信息和第二资源信息不同的情况下，将存储于云平台中的第一资源信息修改为第二资源信息。
S513、客户端基于通知消息，确定第一资源状态信息变化为第二资源状态信息。
在一些实施方式中，客户端可以基于云平台发送的上线通知，显示资源设备上线。在一些实施方式中，客户端可以将资源设备相关的控件重新设置为可触发的控件，从而用户可以通过触发客户端对资源设备进行相应的控制。在一些实施例中，客户端还可以将与资源设备相关的内容采用彩色图像的方式显示，使用户能够清楚的知道资源设备上线。
S515、客户端基于资源属性信息，确定特定资源的资源状态能够恢复。
客户端可以基于第三资源信息中的资源属性信息，或者，基于第一资源信息中的资源属性信息，或者，基于第二资源信息中的资源属性信息，确定特定资源的资源状态能够恢复。
S517、客户端获取第一触发指令；第一触发指令用于指示对资源设备的资源状态进行恢复。
客户端获取用户对客户端进行触发得到的第一触发指令。在一些实施方式中，客户端可以显示是否恢复资源状态的控件，在用户选择是的情况下，客户端可以获取第一触发指令。
S519、客户端向云平台发送恢复请求，云平台接收客户端发送的恢复请求。

S521、云平台向资源设备发送恢复请求，资源设备接收云平台发送的恢复请求。
S523、资源设备将状态恢复至与第一资源状态信息对应的状态。
资源设备可以响应恢复请求，将状态恢复至与第一资源状态信息对应的状态。
在一些实施例中，资源设备可以响应恢复请求，将与第二资源状态信息对应的状态，恢复至与第一资源状态信息对应的状态。
在一些实施方式中，客户端或者云平台中可以存储有关于资源标识和资源是否能够被恢复的对应关系的列表，从而客户端或云平台可以基于该列表确定资源是否能够被恢复。在另一些实施方式中，客户端或者云平台可以直接根据最新接收到的状态信息，确定该资源是否可以恢复，在这种情况下，可以没有资源标识和资源是否能够被恢复的对应关系的列表。
在本申请实施例中，通过云平台确定第一资源状态信息和第二资源状态信息是否相同，使得云平台可以将是否相同的结果告知客户端，从而无需客户端进行第一资源信息和第二资源信息是否相同的计算，进而能够降低客户端的消耗。另外，基于用户触发客户端得到的第一触发指令发送恢复请求，可以使得资源设备只有在用户确认进行恢复时，才进行资源状态的恢复，进而可以使资源状态的恢复根据用户需求进行，提高了资源恢复的可控性。
图6为本申请实施例提供的再一种物联网通信方法的流程示意图，如图6所示，该方法包括：

在一些实施例中，客户端可以显示是否设定资源设备的状态为自动恢复的控件，在用户选择是时，得到第二操作指令，表明客户端可以自动通过云平台向资源设备发送恢复请求来自动恢复资源设备的状态。例如，在设定资源设备的资源状态断电上电自动恢复的情况下，在接收到用户对应的操作时，客户端可以设置资源设备的资源状态为断电上电自动恢复，从而在资源设备断电上电后，自动通过云平台向客户端发送恢复请求。
S603、资源设备向云平台发送第一资源信息；云平台接收资源设备发送的第一资源信息。
S605、云平台向客户端发送第一资源信息；客户端接收云平台发送的第一资源信息。
